High Purity Valves

ConstructionThe GEMU 600 HP 2/2 way valve has a low maintenance piston actuator which can be controlled by inert gases. It has a stroke limiter, a manual override and an integral optical position indicator as standard.Normally Closed, Normally Open and Double Acting control functions are available.

Features

Suitable for inert and corrosive liquid and gaseous high purity media

All medium wetted parts and the housing are made of high quality plastic materials

Valve body: PFA-lnliner/PVDF-Outliner (carbon-filled)

Diaphragm material: PTFE/EPDM

Actuator PP glass fiber reinforced

Control connection in flow direction as standard, therefore installation in restricted spaces possible

Manufactured under cleanroom conditions

Advantages

Good Kv value

Contamination level according to SEMI spec. F 57

Minimal deadleg

Optional flow direction, will seal in either flow direction up to full working pressure

Due to its design particularly suitable for polishing agents and slurries

Optional mounting position

Optional accessories

Electrical position indicator with microswitches or proximity switches

ConstructionThe GEMU 677 HPW 2/2 way diaphragm valve has a low maintenance bonnet with an economically designed handwheel and an integral optical position indicator. All medium wetted parts are made of PFA (body) and PTFE (diaphragm).

Features

Suitable for inert and corrosive liquid and gaseous media, particularly high purity media

All medium wetted parts and the housing are made of high quality plastic materials

Valve body: PFA-lnliner/PVDF-Outliner (carbon-filled)

Diaphragm material: PTFE/EPDM

Bonnet: PP glass fiber reinforced

Assembled, tested and packaged under class 100 cleanroom conditions

Advantages

Good Kv / Cv value

Minimal deadleg

Optional flow direction, will seal in either flow direction up to full working pressure

Due to its design (diaphragm valve, i.e. soft flow deviation) also particularly suitable for polishing agents and slurries
